popping at low rpm

[9150ho]

Just got er done! supercharger is in and the car is running, but its not all right yet. I have the novi 1000, a bosch bypass valve, and the fmu, i think thats about all that would be of relevance. it idles really low at like 500 down to 300 and than will die after a couple minutes or less. and when i acclerate it will stutter and jerk kinda. but its all ok at higher rpm's like if im cruising at around 3000 and up and even under WOT. i really cant take it at wot all the way through the gears because its raining, but any idea on what i can look for with my symptoms? would a vacuum leak cause low rpm troubles but than subside at higher ones?

well the first thing i would do is bump up that idle speed. My car was idleing at 500 for a while and if i hit the gas it would fall on its face. Try setting your idle between 800-1000 See how that does.

what about when i just take off normally from a stop light and it pops and jerks? that wouldnt have anything to do with where the car idleing right?

okay i don't know a lot about this stuff... but I am going to say it sounds like a timing problem or some kind of fuel problem. Maybe to rich or something a little wrong with the timing. Maybe even a small vaccum leak?
